This test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration.
Inductively-coupled plasma/mass spectrometry (ICP/MS)
0-9 µg/L
Blood levels of arsenic have a short half-life and are useful only for monitoring recent or acute exposure. Urine arsenic measurement is a better measure of arsenic poisoning. In addition to pesticides, rodenticides, weed killers, paint, and wood preservatives contain arsenic.
